[0015] A cylinder 10 is fixedly connected to one end of the mounting box 9. The cylinder 10 and the controller 21 are electrically connected. The output shaft of the cylinder 10 passes through the mounting box 9 and extends into the interior of the mounting box 9.

The fixing plate 37 can support the brush wire so that the cutter 40 can cut the brush wire. When the output end of the cylinder 30 drives the brush wire at the gripper 32 to complete the reset conveying, the cutter 40 can cut the brush wire. Then the output shafts of the two cylinders 35 can drive the two rubber seats 36 to retract, so that the two elastic grippers 32 can be reset for the next brush wire conveying movement. The fixing plate 37 is located on one side of the gripper 32. The cylinder model is QGA.
[0019] Both U-shaped plates 3 are fixedly connected to limit rods 24 inside. The inside of the lead screw sleeve 5 is slidably placed on the outer surface of the limit rod 24. The limit rod 24 can limit and guide the two lead screw sleeves 5, so that the guide wheel 7 can move and adjust smoothly, and the guide wheel 7 can stably limit the brush wire. One side of the double-headed lead screw 4 passes through the U-shaped plate 3 and extends to one side of the U-shaped plate 3. Both double-headed lead screws 4 are fixedly connected to one side of a handwheel 25.
[0020] The working principle of the brush wire spot welding device provided by this utility model is as follows: By rotating the two handwheels 25 respectively, the handwheels 25 drive the double-ended lead screw 4, so that the two lead screw sleeves 5 on the double-ended lead screw 4 can move towards each other, so that the two sets of guide wheels 7 can approach each other. In this way, the two sets of guide wheels 7 can simultaneously limit the conveying of the two brush wire bodies 8, ensuring the stability of the brush wire bodies 8 during spot welding. Then, the controller 21 can start the cylinder 10. The output shaft of the cylinder 10 drives the active wedge block 11 to extend and move, squeezing the elastic driven wedge block 13. In this way, the pressure plate 20 at the slider 19 can squeeze and position the two brush wire bodies 8. With the use of the baffle 23, the two brush wire bodies 8 can be tightly attached together to facilitate spot welding, which is beneficial to improving the spot welding effect and ensuring the welding quality of the brush wire spot welding device. Then, the controller 21 sequentially starts the cylinder 27 and the spot welding device body 28. In this way, the cylinder 27 can drive the welding head of the spot welding device body 28 to move downward, so that the welding head can perform spot welding operation on the two brush wires. By tightening bolt 18, the slider 19 can move and adjust within the L-shaped groove 17 of the mounting base 16, allowing for flexible adjustment of the position of the pressure plate 20. This ensures that the pressure plate 20 can more firmly press and position the two brush wires, guaranteeing the spot welding quality of the brush wires. Next, the controller 21 sequentially activates cylinders 30 and 35. At this time, the output end of cylinder 30 drives the two grippers 32 to approach the two brush wires, and the output ends of cylinders 35 drive the two rubber seats 36 to extend together. This allows the two rubber seats 36 to press the two elastic grippers 32, enabling the grippers 32 to hold the two brush wires. Then, cylinder 30 retracts itself to move and transport the two brush wires for continuous spot welding. Finally, the controller 21 activates cylinder 39, causing the output end of cylinder 39 to move the cutter 40 downward, allowing the cutter 40 to continuously cut the spot-welded brush wires to obtain the spot-welded brush wires.
[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
